It's and ER-11, it's metric so 3.175mm. I ran it from an old power supply from a broken treadmill. It actually put out a little over 50 volts DC until you crank it up to the max, then it's about 65 volts. I've got another power supply that's 50 vdc but it's not working. I hope I can get it to work, it would be easy to hook into Mach 3 to power the spindle. Now, I just turn the spindle on and then start the program. If the program stops for some reason, it just sets there and runs until I check on it.
I have to admit, it's hard to walk away from it. I just set and watch it for hours.
my problem with the spindle motor is that I would also have to get a power supply,

now i know I've lost it when I start quoting myself.
But back to the spindle motor, and power supply, if I buy one, the nomenclature says that it will run with 12 to 50 volts, I wonder what sort of power it would have running on 24 volts which I have a power supply rated at.
Any Electronic GURU's out there that may be able to shed some light on the question. Cause if I can get some decent power at 24 volts, I'll get one of these on order by the middle of next week.

Since this is DC, I assume it is using brushes. When those wear out, where do you get replacements. Personally I think 24V is iffy. That would be around 7500rpm if voltage and rpm scale linearly. Will the tooth cut depth be a good match for the speeds and feeds you want? Since this is a 300W motor, I am assuming it could pull as much as 5 or 6 amps. Will your power supply be able to handle that. I see some 0-60V 5A adjustable voltage power supplies going for about $100 on ebay. I would say add one of those in if you get the spindle. Thats my 2 cents worth.

with all that said, I think I'll wait till I can afford one with a VFD. I see no sense in buying the same horse two or three times. I do plan on getting a cheap compact router till I can afford the spindle, or I may just say to hell with it and go in for the VFD unit.

I fired the router up today and ran a part that I had created the code for on Mach3 sim, it said that, (using the 1/8 inch bit biggest bit I can use at the moment),it would take 22.5 hours to cut the pattern. So I guess when I get my check on Wednesday I'll be ordering me up a VFD controled spindle motor with and ER11 collet which will take up to 5/16" bits from what Shars says.

dragged out all the burner junk today and fired up the oil burner to see if the blower that I've used on the last couple of aluminum melts was going to be big enough to attempt to melt iron with WELL it ISN't so back to the drawing board on that issue.
But I did stick an investment in the hot furnace to melt the wax out while the furnace was still hot, which I have since moved over to the electric kiln that I have to finish the heat up to burn out the remaining wax and also melt the small amount of aluminum that I need to make the pour with, so I may get to play with the hot stuff today after all.
Work on the router is on hold due to waiting on parts to arrive from China so that I can reposition a couple of the stepper motors, I have found out that I also can buy the same cutout tool that I have from HF an that it comes with a 1/4" collet so as soon as they open the new HF store thats on my side of town I'm going to get one that I can use bigger endmills for cutters, or use regular 1/4 inch shank router bits.

I have an electric leaf blower that I was trying to use with my oil nozzle. It has too much plastic, the brush holders melted and it quit right about the time everything was getting a good yellow heat. The big blower I have now is 220v and I don't have that in the garage yet. I've been looking at the dust collector blowers at Harbor freight. They are pretty big.
I have a blower that I think will work, just have to make a housing for it, its suppose to be rated at 875 CFM, going to try to get ahousing make next week.
I did have a cordless leaf blower but something fried in it about the time that my 3 amp variac fried so I lost both of those items.

made a road trip today to Guthrie Ok to the yearly machinery swap meet, the swap meet is helt at an old iron foundry and machine shop that has been turned into a museum. Lots of old machinery to look at in a very small place. Here's a photo of the cupola that they used as you can tell from the photo its been a spell since it was fired.
I could sure have some fun there if they would lock me in with the lights left on.
